YES-830I-A2 8" x 30" Variable-Speed
Knee Mill with Ram Head
- YES-830I-A2 Variable-Speed Knee Mill with Ram Head runs on single-phase power using an inverter.
- The state-of-the-art frequency drive inverts and modulates the power to give you smooth speed changes with robust torque.
- Now you can have speeds from 200 to 2250 RPM with just the turn of a dial.
- The head slides in and out, swivels, and tilts 45° left-to-right, enabling extremely versatile operations.
- Features hardened and precision-ground leadscrews, dovetail ways, turret-style column, and fine downfeed on quill.

Milling Machine Features
It is a machine which is used to remove metals from the work piece with the help of a revolving cutter called milling cutter. It is used to machined the flat, rough and irregular surfaces and this is done by feeding the work piece against a rotating milling cutter.
Basically the milling machines are divided into two types first is horizontal milling machine and second one is vertical milling machine. They are further classified as knee-type, ram-type, manufacturing or bed type and planer-type milling machine.
